摘要:Entrepreneurship is believed to be shaped by institutions; however, the paper assumes that trust in institutions is a fundamental prerequisite for the impact of institutions on entrepreneurship. The aims of the paper are to determine (i) whether trust in European institutions affects the level of entrepreneurship in European Union countries, and (ii) whether there are any differences in this impact regarding the types of institutions and (iii) a country’s government budget size. Based on yearly panel data for 27 European Union countries in the years 2004–2019 and estimations of panel regression models, the results show that confidence in institutions is a significant factor in explaining entrepreneurship. However, institutional trust has no homogeneous effect on entrepreneurship, as the impact depends on the kind of institutions related to their functions and values as well as on the country’s characteristics in relation to the size of the government’s budget. Practical implications suggest the possibilities of supporting entrepreneurship—especially in countries with a relatively lower public redistribution—by raising the level of confidence in the European Central Bank. The originality of the paper is related to distinguishing institutional trust based on the type of institutions and the country’s characteristics of governmental budget size.
